摘　　要：目的通过对烤瓷贴面和计算机辅助设计(computer aided design,CAD)与计算机辅助制作(computer aided manufacture,CAM)瓷贴面修复3年后的临床观察和比较,评价 CAD-CAM 瓷贴面的临床效果。方法选取23例患者制作 CAD-CAM 瓷贴面65个,25例患者制作烤瓷贴面105个。修复3年后采用改良加利弗尼亚牙科协会-瑞格标准对两种贴面的各项临床指标、存留率及患者满意度进行比较分析。结果烤瓷贴面和 CAD-CAM 瓷贴面3年存留率分别为96.2%和93.8%;患者满意度分别为92.4%和90.8%。两种贴面在颜色匹配、边缘着色、边缘适合性方面差异无统计学意义。CAD-CAM 瓷贴面表面质地优于烤瓷贴面。结论 CAD-CAM 瓷贴面是一种成功的修复方式。Objective To evaluate the clinical application of a computer aided design and computer aided manufacture （CAD/CAM） veneer system. Methods Sixty-five CAD/CAM veneers were made for 23 patients and 105 porcelain veneers were made for 25 patients. After three years, the clinical performance of two veneer systems were evaluated and compared according to modified California Dental Association/Ryge criteria. The clinical success rate and patient satisfactory rate were calculated. Results The success rates of porcelain veneer and CAD/CAM veneer were 96. 2% and 93. 8% , respectively. The patient satisfactory rates were 92.4% and 90. 8%. There was no significant difference between two veneer systems in color match, marginal discoloration and marginal fit. But the surface texture of CAD/CAM veneers was better than that of porcelain veneers. Conclusions CAD/CAM veneer system was a successful approach for veneer restorations.
